ABSTRACT:
A track circuit retainer clip adapted to be driven on the edge of the base of a rail holds one or a plurality of conductors parallel to and within the rail base edge. The clip comprises a U-shape spring metal clip having a bight portion and upper and lower legs which embrace the rail base edge. The upper leg includes a center spring finger extending from the bight portion which includes two concave side-by-side recesses to hold the conductors against the upper leg. The outer end of the spring finger flares upwardly to facilitate insertion and the lateral edges of the spring finger are bent upwardly to avoid biting into the conductors. The lower leg includes barbs struck from the edge which terminate in truncated biting edges extending substantially parallel to the rail base edge. The line contact transverse the direction of insertion provides ease of insertion and better gripping or holding action without scratching or notching the bottom of the rail.
